Answer:

n ordered pair contains the coordinates of one point in the coordinate system. A point is named by its ordered pair of the form of (x, y). The first number corresponds to the x-coordinate and the second to the y-coordinate. To graph a point, you draw a dot at the coordinates that corresponds to the ordered pair.

Answer:

16 >_ w ( a line under >)

Step-by-step explanation:

Inequalities help us to compare two unequal expressions. The inequality that means the weight of a cat is no more than 16 pounds is 16>w.

Inequalities help us to compare two unequal expressions. Also, it helps us to compare the non-equal expressions so that an equation can be formed.

It is mostly denoted by the symbol <, >, ≤, and ≥.

Given that the weight of any cat in the local animal shelter is no more than 16 pounds. Now, w be the weight in pounds of a cat in the shelter. Therefore, the inequality that means the weight of a cat is no more than 16 pounds is 16>w.

Answer:

a=16

Step-by-step explanation:

a*2+ 12*2 = 20*2

12to the power of 2 is 144

20to the power of 2 is 400

a*2+ 144 =400

-144. -144

a*2= 256

find the square root of 256 which is 16

so there for 16 is the answer

Answer:

Step-by-step explanation:

First switch the y and x values:

[tex]x=3^y[/tex]

Take the natural log of both sides to get:

[tex]\ln(x)=y*\ln(3)[/tex]

Separate the y value:

[tex]y=\frac{\ln(x)}{\ln(3)}[/tex]

The inverse of the exponential function will be:

"y = [tex]\frac{ln(x)}{ln(3)}[/tex]".

According to the question,

The function, y = [tex]3^x[/tex]

By switching "x" and "y" of both sides of the function,

→     x = [tex]3^y[/tex]

Now,

By taking "log" both sides,

 ln(x) = y × ln(3)

By separating the terms, we get

      y = [tex]\frac{ln(x)}{ln(3)}[/tex]

Thus the above response is correct.

y=10 x=30

Step-by-step explanation:

3x=90

x=30

2(30)+3y=90

60+3y=90

3y=30

y=10

Answer:

y= 10

Step-by-step explanation:

we have to find x first

∠ABD= 90° because its a right angle

3x°=90°

divide by on both sides

x= 30°

∠CBD must equal 90° degrees as well because a line is 180°

60+3y= 90

Answer:

[tex]Speed = 2519.58 mph[/tex]

Step-by-step explanation:

Given

[tex]Distance = 6417.5km[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Required

Calculate the speed in miles per hour

Convert distance to miles

[tex]Distance = 6417.5km[/tex]

[tex]Distance = \frac{6417.5km}{1.609}\ miles[/tex]

[tex]Distance = 3988.50217526\ miles[/tex]

[tex]Time = 1\ hr: 35\ mins[/tex]

Divide minutes by 60

[tex]Time = 1\ hr + 35/60[/tex]

[tex]Time = 1\ hr + 0.583\ hr[/tex]

[tex]Time = 1.583hr[/tex]

The speed is:

[tex]Speed = Distance/Time[/tex]

[tex]Speed = 3988.50217526/1.583 mph[/tex]

[tex]Speed = 2519.58 mph[/tex]

Answer: Decay bc its less than 1.00 (proven by the exponential decay equation)

Step-by-step explanation:

percent would be 1.00-0.96= 0.04 , 4%

Step-by-step explanation:

Let's pick some easy numbers for illustration.

Let x equal our initial stock purchase, and, say it was $100.

x = $100

The problem says it's value dropped by 17.2%. If x = 100 is 100% of our stock value the 17.2% less is

[tex]x - 0.172x = 0.828x[/tex]

So now our stock is worth 0.828(100) = $82.80.

Now how much of an increase do we need to get back to $100.

[tex]100 - 82.80 = 17.20[/tex]

So our base is $82.80 because our stock price dropped, we want to know what percent increase is $17.20 of $82.80

[tex]17.20 \div 82.80 = 0.2077[/tex]

Or 20.77% increase to get back to original price.

To make this generic, since $100 is not supplied information, substitute x for 100 and 0.828x for the amount of money dropped.

x = original stock value

[tex]x - 0.828x [/tex]

Is the amount of value lost, and to be regained in the second part of the question.

To find out what portion the decrease is of the new value

[tex] \frac{(x - 0.828x)}{0.828x} = \frac{0.172x}{0.828x} = 0.2077 [/tex]

Or 20.77%

Answer:

2 i think i dint sleep last night sorry if im wrong

Step-by-step explanation:

Find total mass:

Human: 65 kg x 6,840,000,000 = 444,600,000,000 kg

Ants: 4x10^-3 = 0.004g

0.004 x 10,000,000,000,000,000 = 40,000,000,000,000g

Divide total grams by 1000 to get kegs:

40,000,000,000,000 /1000 = 40,000,000,000 kgs.

Divide total mass of humans by total mass of ants:

444,600,000,000 / 40,000,000,000 = 11.115

Mass of humans is 11.115 times more than ants.

Rounded to the nearest whole number = 11 times more.

============================================================

Explanation:

The square marker indicates a 90 degree, or right angle.

The two smaller angles (3x and 75) both combine to the larger 90 degree angle. That's what it means when they say we have complementary angles.

Add up the smaller angles, set the sum equal to 90, and solve for x.

3x+75 = 90

3x+75-75 = 90-75 ....... subtracting 75 from both sides

3x = 15

3x/3 = 15/3 ..... divide both sides by 3

x = 5

---------------

If x = 5, then 3x = 3*5 = 15

Then we can see that 15+75 = 90 to help check our answer.

Answer:

8/15 or 8 over 15 should be the answer
